What were the concerns you saw about Mailbox? I’ve been using it (and addy.io) a while as part of my move away from Proton, and I have no complaints thus far. It works with my email app nicely, which is a big reason I like it over Tuta, although Tuta is pretty nice as well, as long as you don’t mind using their app.
Mullvad. Excellent service, never had an issue. Used to use Proton, but their CEO sucks ass
